Answer 1

Step-by-step explanation:

The average of the remaining numbers will be 37.5.

Solution:

The average of 50 numbers is 38

We know that,

\text { Average } = \frac { \text { Sum of the observations } } { \text { Total number of Observations} } Average =

Total number of Observations

Sum of the observations

Here, total = 50 and average = 38

The sum of all the 50 numbers are = 50×38 = 1900

The Sum of the given two numbers = 45+55 = 100

After discarding two numbers, total numbers left now are = 48

The total sum of the remaining 48 numbers are = 1900-100 = 1800

∴ The remaining average of the 48 numbers are

= \frac {1800}{48} = 37.5=

48

1800

=37.5

Thus, the average of the remaining numbers will be 37.5.
